Hi all, still very new to the forum and audis in general. This is my first 4wd car and im currently in the hunt for some new rims, the car is a 2000 W and is running standard 17" avus s4 wheels. From what i have read previously the width of these alloys is 7.5j. Im looking at merc and vw rims but alot of them seem to be different widths front to back - i.e. 8.5j front and 9.5j rear .. .. ..my questions is will this difference in width affect the 4wd system? Or is anyone running this sort of setup already without any problems? Help much appreciated, Mitch.
